Harley Pasternak leads a group workout in Montauk, New York, at a launch event for Fitbit's newest products including its first ever smartwatch.

With a client list stockpiled with A-listers, including Katy Perry, Rihanna, Shay Mitchell, Ariana Grande, and more, you'd think that renowned trainer Harley Pasternak would give out fitness advice that sounds just as exclusive. But while his current and former trainees may be on another level, there's nothing fancy or elite about the core health recommendations he gives them all.

There are five of them he swears by, to be exact, and they're not all about what you're doing at the gym. Maintaining an all-around healthy lifestyle is about so many different factors, including how you're eating, sleeping, relaxing, and moving when you're not working out, Pasternak tells SELF.

Granted, celeb clients may have more involved regimens for reaching specific health and fitness goals, but when it comes to living your best, healthiest life, these are the basic habits he says everyone needs. There are no complicated workouts or specific eating plans required—just consistency and commitment to these five simple rules.

1. Get at least seven hours of quality sleep every night.

Pasternak stresses that sleep is just as important as the workouts you do and the food you eat. "When you're growing a flower, what's more important, oxygen or water? You can't have one without the other," he says.

So, seriously—it's time to prioritize sleep once and for all, because not getting enough zzz's can completely sabotage your other healthy lifestyle efforts and alter how you feel every day. "Lack of sleep impacts the hormones in your body that affect appetite, [as well as] metabolism, energy, and mood," Pasternak says. He adds that when you're sleep deprived, "you're less likely to make good food choices, and you're less likely to be active." Among other consequences, research shows that skimping on sleep increases levels of the hormone ghrelin, which tells your brain you're hungry, and decreases levels of the hormone leptin, which sends the message that you're full. Plus, working hard at the gym is far less appealing when you're exhausted.

It's not just about quantity, though. "Some people might sleep eight hours and wake up exhausted because they're not getting good quality sleep," says Pasternak. So if you're not waking up feeling rested, troubleshoot by investigating what might be messing with your beauty rest—maybe you're looking at your phone in bed (blue light suppresses the production of the sleep-regulating hormone melatonin), drinking caffeine late in the day, or you have a bed partner who snores.

2. Take at least 10,000 steps every day—but aim for 12,000.

While walking may sound borderline outdated in an age where high-intensity, balls-to-the-wall workouts are considered the gold standard, Pasternak stresses that you should be moving as much as possible when you're not working out too.

"There are 168 hours a week, and if you're in the gym for three of those, you're still not in the gym for 165 of those," he says. "And it's the movement you produce outside the gym that reduces the amount of time you need to spend in the gym." Simply walking more is a great way to add more movement to your day wherever you are.

And while 10,000 is a good start, he says you should consider it a minimum, not a target. "If you really want to thrive, I would say you need a minimum of 12,000 steps a day," says Pasternak. Research isn't conclusive when it comes to pinpointing a magic number of steps we should take—rather, different studies suggest different step minimums may be ideal for different health outcomes, like weight loss, improving sleep, or reducing risk of cardiovascular disease—yet one thing remains true: the more steps, the better.

Take a walk during your lunch break, walk short errands—just do whatever you need to do to add more walking to your day.

3. Unplug from technology for one hour every day.

Possibly the most unexpected health advice on Pasternak's list is doing a mini digital detox every day. "For at least one hour, unplug from any active technology—unplug from the constant alerts, vibrations, emails, Instagram DMs, texts, and phone calls," says Pasternak. This means putting your phone away, shutting your laptop, powering down your tablet, and turning off notifications on your smart watch. (Passive technology, like music playing, is fine in his book.)

He sees this as a form of meditation for people who aren't into, you know, actual meditation. "Really, it's about taking care of yourself," he says, which is something we often forget to take the time to do when we're consumed with who's posting what on Instagram. By detoxing, you're giving yourself a mental break, and that can help manage stress, which isn't great for your mind or body.

4. Eat a balance of protein, fiber, and healthy fats five times a day, and stay hydrated.

Eating well is a major component of Pasternak's philosophy. And while there are many different ways to eat healthy, Pasternak suggests focusing on three key nutrients: protein, fiber, and healthy fats.

A balanced diet of these three macronutrients gives your body the fuel it needs to do everything from think to run. Also, "those are three nutrients that lead to satiety," Pasternak says. By incorporating each of these every time you sit down to a meal or snack, you'll feel more satisfied and stay fuller for longer—your body can use all of these things to get nutrients and energy, versus a snack full of empty calories like refined sugar that can leave you feeling hungry or sleepy once the initial high wears off.

For most of us, the five-times-a-day rule fits in with the habit of having three meals and two snacks, says Pasternak. "It's probably not too much of a departure from what you're currently doing," he says.

He also says to make sure you're staying hydrated. Thirst can sometimes present itself as hunger, not to mention that being dehydrated can make you feel crummy, and even impact your ability to get in a great workout. Keep a bottle of water by your side throughout the day to remind you to drink up.

5. Fit in five minutes of resistance training exercise every day.

You read that right: five minutes. "You don't have to spend any days in the gym," according to Pasternak (if you don't want to, that is). Unless you have specific fitness goals or you're training for a race or event, Pasternak says maintaining a healthy lifestyle can take as little as five minutes of targeting one muscle group, or even just doing one resistance exercise a day.

"Pick a different move every day of the week, each representing a different body part," Pasternak suggests. For example, "day one could be four sets of 20 reps of reverse lunges. You don't even need to put on a gym outfit," he says. The next day, you could focus on push-ups, followed by plank variations the next day. In one week, you'll be able to fit in all of your major muscle groups, and you can choose different exercises for the following week.

If five minutes a day sounds too good to be true, it's important to keep in mind that practicing all five healthy habits is what leads to a well-rounded, healthy lifestyle, says Pasternak.

"If you omit any one of the behaviors you can't compensate by doing extra of any of the others," he tells SELF. Sure, it's easier said than done, but in the name of living your best life, it's totally doable. And most importantly, maintainable.
